# tools/selfhost/program_analyze.sh - Phase 160-impl-1 Program JSON Analyzer wrapper
#
# Usage:
#   ./tools/selfhost/program_analyze.sh /path/to/program.json
#   ./tools/selfhost/program_analyze.sh < program.json   # stdin
#
# This script reads a Program JSON v0 file and passes it to the .hako analyzer
# for selfhost depth-2 verification (Rust outputs IR → .hako reads IR).
